A client's blood pressure drops suddenly from 160/90 mmHg to 60/40 mmHg minutes after the nurse administers a 0.3 mg sublingual dose of nitroglycerin for chest pain. The client reports crushing chest pain, severe nausea, dizziness, and left arm numbness. Which intervention should the nurse implement?

A client's blood pressure drops suddenly from 160/90 mmHg to 60/40 mmHg minutes after the nurse administers a 0.3 mg sublingual dose of nitroglycerin for chest pain. The client reports crushing chest pain, severe nausea, dizziness, and left arm numbness. Which intervention should the nurse implement?

• A. Place client in Trendelenburg
• B. Check airway; wait and observe
• C. Administer another nitro
• D. Infuse a rapid 0.9% normal saline bolus

Answer: (D)

When a nitrate causes a dramatic drop in blood pressure, the priority is to stabilize hemodynamics and restore perfusion. Nitroglycerin dilates veins and arteries, decreasing preload and systemic vascular resistance; if the BP falls to 60/40, continuing or repeating nitro would worsen hypotension and tissue perfusion. Giving a rapid normal saline bolus increases intravascular volume, raises preload, and helps raise both blood pressure and coronary/brain perfusion. This intervention addresses the immediate problem of hypotension while the team reassesses chest pain and pursues definitive management for suspected acute coronary syndrome. Other options don’t address the urgent need to raise blood pressure. Trendelenburg is not reliably safe or effective for profound hypotension and can have harmful effects. Simply checking the airway and observing delays corrective action for a life-threatening drop in BP. Administering more nitro would worsen the hypotension. After the fluid bolus, vitals should be reassessed, nitro should be withheld, and ACS management continued.
